To all whom it may concern.-

Be it known that I, EMIL SonAFrNna, a citizen of the United States,residing at Wimbledon, in the county of Barnes and State of NorthDakota, have invented a new and use' ful ConveyersApron, of which thefollowing is a specification.

- This invention relates tononveyer-aprons, and 'is particularlydesigned for use upon binders and other agricultural machines.

Heretofore considerable difficulty has been experienced with the apronsof machines of this character, because the straw often becomes' wedgedbeneath the slats on the apron and. breaks them and is also sometimescarried around by the apron, thereby seriously interfering with theoperation of the machine.

The-object of the present invention is to provide an'apron which will'obvi'ate'these disadvantages.

, With these and other objects in view the invention consists of certainnovel features of construction and combinations of-parts,

which will behereinafter more fully described, and pointed out in theclaims.

Inthe accompanying drawings is shown the preferrefgiijorm of theinvention.

In said ings, Figure 1 is a view showinga portion of a conveyer beforethe same has been folded over the slats thereof. Fig. 2 is a plan viewof a portion of the finished conveyer, the fabric being spread apart atone corner; and Fig. 3 is a longitudinal sec tion through a portion ofthe conveyor.

Referring to the figures byv characters of reference, 1 IS a strip ofcanvas or other su1table material of double width, and secured upon thisstrip and extending, preferably, about half-way across thesame are slats2,

said slats being fastened in place byrivets 3 or in any other preferredmanner.

That portion of the strip 1 extending, beyond the ends of the slats isfolded thereover to form an upper strip 4, and this upper strip restsagainst the rear faces of the slats and is then sewed, as at 6, so as topresent a smooth shoulder extending at right angles from the apron.Those portions of the upper strip 4 .in front of the slats are seweddown at points removed from the faces of the slats, as shown at 7, so asto produce inclined portions 8; This upper strip 4 is preferably leftloose to a certain extent, so'that when the apron passes around its sup'orting-rollers there will be no danger o the seamssurfaces 8 willprevent the apron from carry ing the straw around with it, and therebyinterfere with the o aeration of the machine. Straps 10 are pre erablysecured iongitudi-;' nally under one end of the strip 1', and buckles"11 are secured adjacent the other end thereof.

A large number of sections such as described canthereforebe fastenedtogether by means of these buckles and stra .s, so as to form acontinuous apron of any esired proportions.

Although the apron-section has been described and shown as formed in asingle width of fabric, it is to be understood that, if preferred, thetop and bottom strips may be separate and can afterward be securedtogether along their front edges.

By the term slat used by me in refers ence to the part 2 it is to beunderstood that I do not mean to restrict myself. to a strip 2' ofanyparticular form or material, as said strip can be made of wood,leather, rope, or,

in fact, anything, whether flexibleor rigid,

- with which the proper resultscanbe obtained.

The preferred form of the invention has been set forth. in the foregoingdescription; but I do not. limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing the advantages thereof, and. I therefore reserve the ri htto make, such changes as fairlv fall within the scope, of the claims.
